The fit was good right out of the box, all twelve; the material does not cut at the edges, the length of the strike tip is close to ideal in my preference - just a bit too long, close enough to file rather than cut. The curve in the strike tip forward edge is not helpful to me, but easily removed.

The softness of the material means a bit of drag on the string, audible and felt - tried polishing the strike tip, bending it back more than usual, and that helped some. With some more fiddling around, I think that will be mostly a non-factor.

Very comfortable, compared with other picks of its kind. Snug but not cutting, shaped to avoid digging into the nail edge or bed, wide enough at the right places, solid feel at string contact.

My only change would be to a harder, smoother, slightly thinner, celluloid or similar, to shed the heavy strings I use more cleanly and quickly. I think that could be done without sacrifice of comfort, given this quality of shape.

Some reviews complained about size being too small. Not so. I have kind of a chunky thumb and they fit me perfectly and stayed put comfortably without being too tight. They are better form-fitting than other brands I tried. I thumb-pick a Rickenbacker bass pretty aggressively, and after a full gig I realized these picks did the job without even realizing they were there, and sounded great. I'll buy more for sure.

Got these for my daughter and tried them out myself. Took a few minutes to get used to but made the transition from using a pick to finger picking very easy, no fumbling with a pick or dropping it. I still prefer a standard pick but can see where these would be great for certain arrangements.All they had was large, worked for me, I cut some and resized them with a heat gun to give my daughter a custom fit.

I believe these thumbpicks are a bit softer material which accounts for the more comfortable fit and the tone balances well for fingerpicking style. I play bluesharp in a neck rack with a Strnad harmonica mic with either my Epiphone EL00 acoustic or a 1956 Gibson archtop and use these picks exclusively be it alternating baselines when fingerpicking or picking/strumming when I want a bit more attack than using the finger(s). No actual features to comment on. I like the appearance and fit. I do not have very large hands, but these picks are more comfortable than the large Dunlops that I had used previously.Quality seems very good. Price is good.

Great product. Too small for a man's thumb. Good price.Nice enough picks. Way too small for my thumbs, and I have small hands for a man. For a woman or a kid they might work, but not for me. The plastic is very rigid. No flexibility to open them up a little more. They feel like they're going to snap. I maybe could heat the plastic and try that. That might work. They should make an extra-large size, but they don't.
